Mathematics – Stage 1 – Year A – Unit 9
This sample Stage 1 unit explores the big idea of combining and separating quantities.
Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.
Students are provided with opportunities to:
- represent combining situations in different ways through the use of gesture, enactment, drawings, numbers, and words
- use symbols to describe mathematical quantities, actions, and relationships in efficient ways
- understand that the order in which 2 quantities are combined does not change the result
